SHUTTLE.

QPEGIFIGATION forming part of Letters Patent No. 743,937, dated November 10, 1903.

Application filed June 26. 1903. v Serial No. 163,228. (No model.)

To a) whom, it may concern:

Be it known that I, J AMES C. SEneEsoN, a

citizen of the United States, residing in the.

cityand county of Philadelphia, State of Pennsylvania, have invented new and useful Improvements in Shuttles, of which the following is a specification.

My invention consists of an improvement in a shuttle whereby the same may be conveniently threaded without liabilityof the filling yard or thread returning to the bobbin or cop, as will be hereinafter set forth.

Figure 1 represents a top or plan View of a portion of a shuttle embodying my invention, a portion of the same being broken away. Fig. 2 represents a side elevation thereof. Fig. 3 represents a horizontal section on line a; .r, Fig. 2. Fig. 4 represents a transverse section on line 'y y, Fig. 2. Fig. 5 represents a perspectiveview of athreading-eye employed on an enlarged scale.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the body of a shuttle, which, excepting the features of my invention applied thereto, is of usual construction. In a transversely and horizontally extending opening in the side of said body is the threading-eye B, and on the upper face of saidbody, above said eye, isthe guidingplate 0. In said body, below said plate 0, is the channel'D, into which the filling thread or yarn is primarily introduced after being run 0d from the bobbin or cop on the shuttle. In the side wall of the body, between said plate C and the periphery of said eye B, is the throat E, which is in communication with the terminal of said channel I).

In the wall of the eye B, which is of substantial thickness is the throat F, which extends obliquely from the periphery of said eye inwardly and is then deflected obliquely in the opposite direction,as at G,t0 the central opening 11 of said eye, thus forming a communication between the throat E and said central opening.

The outer face of the'eye is countersunk, as at J, leaving the flat rim K at the periphery. The eye is secured to the body by means of the screw or pinL (shown in dottedlines, Fig. 4) or by other means in any suitable manner. Theplate O is secured to thebodyAby means of the screw 0 and the usual tension-post 0 said screw passing through said plate into' said body and said post rising from the interior of said body and being connected with said plate.

The operation is as follows: The filling is passed from the bobbin or cop under the plate 0 and around the post C through the channel D until it reaches the throat E, when it descends the same and enters the throat F and traversing the latter is discharged into the eye 13, leaving its end on the exterior of said eye, it being noticed that should the portion of the filling outside of the eye run around said eye the countersink .T, assisted by the obliquely or diagonally extending throat F, will keep said portion at the periphery of the eye, especially on the rim K, and so prevent it from reentering the throat F, whereby it cannot return through said throat, the throat E, and the channel I) to the bobbin or cop, but, on the contrary, retains its proper position in the eye B, so that the filling will be properly run off without liability of fouling with the bobbin and stopping of the work.

By the term countersunk it is evident that I intend a hollowing out or beveling of the wall of the eyesuch, e. g., as would be made for the reception of an ordinary screwhead.

Various changes may be made in the details of construction shown without departing from the general spirit of my invention, and I do not therefore desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. In a shuttle, a threading-eye having a wall of substantial thickness the exterior face of which is countersunk, said wall having a throat extending in a non-radial line there;

through.

2,. In a shuttle, a threading-eye having a wall of substantial thickness the exterior face of which is countersunk, said wall having a deflected throat extending in a non-radial line therethrough.

3. In a shuttle, a guiding-plate, tensionproducing means beneath said plate, a-channel beneath said plate, a throat leading from 10 said channel and a threading-eye having a Wall of substantial thickness, the exterior face of which is countersunk, said Wall having a throat extending in a non-radial line theret-hrough and connecting with said first-named throat with which it forms an angle.
